An Ashghal statement explained the network started operations covering Al Muntazah, Rawdat Al Khail Street, and New Slata up to Al Hilal area along C-Ring Road. This comes as part of Ashghal’s efforts to provide safe and eco-friendly sewage networks that meet the needs of residential and commercial areas around Qatar.
Engineer Ali Mostafawi from the Drainage Networks Projects Department said the sewage network built about 20 to 30 years ago in the interior areas (Inner Doha) with diametres between 150mm and 200 mm has been upgraded to start with a minimum of 300mm up to 600mm diametre. He said this will help avoid long-term leaks and also contribute to reducing maintenance cost.

He explained that the project included improving the conveyance capacity of 24.5km of main sewage pipelines, constructing 855 additional main sewage manholes (with diametres of 1,200 and 1,500 mm) in addition to developing approximately 12km of house connections to serve about 1,277 plots in Al Muntazah, Rawdat Al Khail Street and New Slata up to Al Hilal.
The works are aimed to enhance the efficiency of the sewage network in a safe and eco-friendly manner and to protect the soil and groundwater from pollution.
“Ashghal took into account the expected increase in population density during the FIFA World Cup Qatar 2022 in terms of the number of residents in hotels and all places designated to serve visitors. Accordingly, the sewage network was renewed to accommodate the expected increase in the quantities of wastewater flows during this period,” he noted.
As part of its efforts to support local manufacturers and locally made products, Ashghal was keen to supply all types of raw materials used in this project through the Qatar Primary Materials Company (QPMC). This included 100% local materials such as rubble, coarse sand, fine sand, in addition to other materials such as ready-mix concrete, asphalt materials for roads, glass reinforced fibre pipes (GRP liner used for corrosion protection at inner face of the manhole), waterproofing materials for rooms (protective panels, main insulators and coatings), and steel reinforcement.
Also, Ashghal was keen to speed up the pace of project implementation, as the project works were completed ahead of schedule. Adherence to all safety precautions at work sites contributed to achieving 3mn working hours without lost-time injuries.
